The 65 watt charger is basically the same device we saw back in January: Dart is around a four-times smaller than a typical laptop charger, and it sports a USB charging port. Dart could easily find an audience among consumers who don’t want to be encumbered by bulky chargers — especially since our laptops are also becoming thinner and lighter every year.

Finsix has already raised more than $6 million from Venrock and angel investors, so I asked CEO Vanessa Green why the company needed a Kickstarter campaign:

“The [venture] investment has really been about taking the technology out of the lab and into the real world,” Green said. “We wanted to get engaged with customers, get feedback, and build those relationships. We felt a Kickstarter campaign is a good way for us to engage directly with users.”

Finsix CTO and cofounder Anthony Sagneri spent years developing the core technology, which can cycle power more than 1,000 times faster than existing laptop chargers, at MIT. The company has also hired several renowned engineers in the power space, including its director of technology integration, Jim Kardach, who previously served as Intel’s chief power architect.

Early Kickstarter backers at the $79 level can nab their own Dart, a $40 discount from the eventual retail price. MacBook owners, unfortunately, will need to shell out $148 for a Dart compatible with Apple’s charging technology. (Since the Dart is only a 65 watt adapter, it won’t power large MacBook Pros that need more juice.)

The company expects to start shipping its first Dart units in October.
